Objective: To observe the clinical effect of electroacupuncture at Baliao points in patients with erectile dysfunction after stroke.
Methods: A total of 58 patients with erectile dysfunction after stroke were randomly divided into an observation group (29 cases, 1 case dropped off, 1 case discontinued) and a control group (29 cases, 1 case dropped off). Both groups were given basic treatment, including routine medical treatment, routine acupuncture treatment, rehabilitation training and pelvic floor biofeedback electrical stimulation treatment. The observation group was treated with electroacupuncture at Baliao points, and the control group was treated with shallow acupuncture combined with electroacupuncture at the control points (8 points at 20 mm horizontally beside Baliao points), continuous wave, frequency in 50 Hz, current intensity in 1-5 mA, 5 times a week for 4 weeks. The 5-item version of the international index of erectile function (IIEF-5) score, erectile dysfunction effect on quality of life (ED-EQoL) score and pelvic floor muscle contraction amplitude were compared between the two groups before and after treatment.
Results: After treatment, the IIEF-5 scores and the contraction amplitude of fast muscle fiber, comprehensive muscle fiber and slow muscle fiber in the two groups were higher than those before treatment (P<0.05), the ED-EQoL scores were lower than those before treatment (P<0.05), and the changes of above indexes in the observation group were larger than the control group (P<0.05).
Conclusion: Electroacupuncture at Baliao points can improve the erectile function of patients with erectile dysfunction after stroke, increase the contraction amplitude of pelvic floor muscles, and promote the quality of life of patients.
目的：观察电针八髎穴治疗脑卒中后勃起功能障碍的临床疗效。方法：将58例脑卒中后勃起功能障碍患者随机分为观察组（29例，脱落1例、中止1例）和对照组（29例，脱落1例）。两组均予基础治疗，包括常规内科治疗、常规针刺治疗、康复训练和盆底生物反馈电刺激治疗。观察组加用电针八髎穴治疗，对照组于八髎穴旁对照点（八髎穴水平向外旁开20 mm处的8个点）浅刺联合电针治疗，予连续波，频率50 Hz，电流强度1~5 mA，均每周治疗5次，连续治疗4周。分别于治疗前后比较两组患者国际勃起功能指数（IIEF-5）评分、勃起功能障碍患者生活质量问卷（ED-EQoL）评分和盆底肌收缩幅度。结果：治疗后，两组患者IIEF-5评分及快肌、综合肌、慢肌收缩幅度均较治疗前升高（P<0.05），ED-EQoL评分均较治疗前降低（P<0.05）；且观察组上述指标变化幅度大于对照组（P<0.05）。结论：电针八髎穴能改善脑卒中后勃起功能障碍患者的勃起功能，增加盆底肌收缩幅度，提升患者生活质量。.
